Should he stay or should he go?

The England Rugby team have broken a number of records this world cup, sadly none of them are postive. We are the first host nation to fail to make it out of the group stages, we are the first former winners not to make it out of the group stages, and our defeat against Australia at home was by a record margin. And so rightly or wrongly people are calling for Stuart Lancaster to either step down or be removed. I thought it might be nice to look at the facts of the situation in an objective way.
